Can this be used on fruit trees and bushes? Particularly pear and citrus.

This product is only for use on ornamental flowers and shrubs. If you would prefer systemic insect control on citrus and pear trees I would recommend applying our Fruit, Citrus, & Vegetable insect Control product. Jessica

Thanks, but I need something for fungus control on my pear trees. The trees are large enough where spraying isn't really a viable solution.
